Does anybody know what driveshafts will interchange? I'm looking for a shaft for a single cab long bed 2wd and not having much luck. How about one from say an extended cab short?

 

I'm not an expert, but from talking with the shop yesterday (Just had front shaft rebuilt), Chrysler used a lot of different sized driveshafts for the Ram trucks. As there isn't really a standard i would stick with a shaft from the same style of truck. Just my $.02
